Electrical contactor with positive temperature coefficient resistivity element |
摘要 |
The present invention provides an electrical contactor for connecting and disconnecting an electrical power source to an electrical device wherein the electrical power source is electrically connected to a line terminal having a line terminal electrical contact and the electrical device is electrically connected to a load terminal electrical contact. The electrical contactor contains a plurality of electrical contacts which contact the line and load terminal electrical contacts. A positive temperature coefficient resistivity element is electrically connected between at least one of the terminals and the electrical contactor contacts to provide arc suppression during the opening and closing of the electrical contacts
